The woman left, Zhang Leifeng's new life began, he sat on the sofa and tilted his head back, and when he looked up, he found that there was a thing on the ceiling that was shining with red light, seeing this, Zhang Leifeng squinted his eyes.

Hehe, you're still using a listening device with me, hey, what a boring trick.

After a short daze, Zhang Leifeng returned to his normal state, and the listening equipment was of no use to him. Because as long as I want to transmit something or something out, I won't let them know about it at all.

If you can't do such a thing, then you really don't need to be a suspense detective, just be an ordinary man.

Zhang Leifeng's matter has been solved for the time being, but Xing Dongjie has encountered a big problem here.

A squad that came out to rob in the middle of the night has already created five cases in the city, and one of them has caused casualties, and the superior leaders attach great importance to this matter.

"Get me this case in fifteen days." The director ordered Xing Dongjie very seriously.

Xing Dongjie tilted his head and replied loudly, "Yes." ”

"I'm telling you, this incident has a very big impact on the city, it seems to be a robbery, but it is related to a lot of women who work night shifts, since this case, most women are afraid to go out late at night, and many people who work in 24-hour convenience stores also express fear."

"I hope you can understand that only if we catch the real culprit as soon as possible can the people of the city be relieved." The director said to Xing Dongjie.

Xing Dongjie took a deep breath: "Director, don't worry, I will arrest these guys even if I dig three feet into the ground." Gritted his teeth and replied.

"Okay, I'm relieved to have your words, go get busy, and report to me immediately if there is any situation."

"Yes."

Xing Dongjie left the director's office and joined in the investigation of the case with two teams.

One team visited the perimeter of the crime scene, investigated, found witnesses, and looked for surveillance video, and another team assisted the traffic police to conduct a survey of motorcycles in the city.

"Remember, we only have fifteen days, and I don't want to hear you say we're tired during that time, understand?"

"Understood."

"Okay, let's go."

Police cars drove out of the compound of the Public Security Bureau one after another, and Xing Dongjie drove to the scene of the crime with three people.

Xing Dongjie parked the car five meters away from the scene of the crime, then got out of the car, and squatted on the ground to scan forward according to the steps that Zhang Leifeng had taken to solve the case.

This sweep, he found that there was a not very obvious tire wear mark on the ground, when he saw this, Xing Dongjie's face showed a trace of excitement, and he walked quickly to this trace.

"Don't step on it." The police officer who followed him next to him almost guessed this trace, and was severely reprimanded by Xing Dongjie.

Xing Dongjie squatted here, looking down at the marks on the ground.

"Give me a ruler." Turning to the officer, he said.

The police officers were stunned for a moment: "Captain, we are not forensic doctors, and we don't have rulers with us." He replied helplessly.

Xing Dongjie was stunned for a moment, and then continued: "Then notify the forensic doctor and let them arrive at the scene immediately." ”

"Yes! The command center, the command center, immediately notified the forensic doctor to go under the Sifeng Bridge. ”

"Command center received."

Xing Dongjie never left this line from the time he called the forensic doctor until the forensic doctor arrived, he kept staring at this trace with both eyes, and he began to think about what kind of motorcycle wheel mark this trace would be, but he couldn't remember it after thinking about it for a long time.

There's no way, I don't have too little observation of motorcycles on weekdays, not to mention motorcycles, and even the wheel traces of cars I don't deliberately observe, unless there is a case.

Now it seems that Zhang Leifeng is not without any reason to read all kinds of books, this is definitely a magic weapon to win, it seems that he has to study all kinds of books when he is fine.

When the forensic doctor arrived at the scene, Xing Dongjie signaled to none of them to come, but asked the police officer to hand over the ruler.

I measured the width of the wheel with a ruler, and muttered: "The diameter of the brake mark is ten .6 inches, how wide does this have to be?" Road races? Harley? Or some motorcycles that have been modified? And through these traces, it is obvious that this is not a sudden braking, if it is a speeding car robbery, then when moving to the victim's side, they can only succeed once without sudden braking, which is a bit strange. Xing Dongjie's mind kept automatically playing the pictures he imagined.

He has been learning to reason according to Zhang Leifeng's reasoning method during this time, but in fact, he doesn't know that the picture imagined in Zhang Leifeng's mind and the picture he thinks about now are completely different things.

One is to rely on careful logic and then make some calculations, and the other is to rely on imagination to calculate, how can such calculations become true?

Of course, after N times of reasoning, Xing Dongjie decisively gave up Zhang Leifeng's method, and he decided to judge obediently according to his own method.

After Xing Dongjie measured all the data and took photos from all angles, he turned around and waved his hand to the police officer behind him: "Come here." said.

Everyone gathered around, squatted beside Xing Dongjie, and looked down at the brake mark on the ground.

"Look, it's a brake mark, and who knows what type of motorcycle it's on?" Xing Dongjie asked the others.

Everyone lay on the ground and looked left and right, and then replied to Xing Dongjie: "Captain, according to my thoughts, this is a tire used on a road racing motorcycle, because our ordinary motorcycle tires cannot be so wide, and they are not matched." One of the officers said with a frown.

Xing Dongjie nodded, turned his head to look at the others: "Do you have any better ideas?" He asked.

Everyone was silent, everything they wanted to say had already been said by the guy just now, and the addition must not exist.

Xing Dongjie got up from the ground, patted the dust on his knees, stood here and looked ahead, his eyes narrowed, and his mind kept thinking, what was the situation?

With these questions, Xing Dongjie returned to the public security bureau with the police after repeated searches at the scene.

After more than two hours, all the people who had gone out returned to the Public Security Bureau.

Xing Dongjie was immediately anxious for everyone to hold a meeting to discuss and study this matter.
